Although this may yet prove to be false controversy, I have to admit to being tired of potentially good games having so much difficulty getting ported over. Fire Emblem has always played on the fantasy of being a strong, charismatic and compassionate leader who can change the world through the power of friendship and without adding any wild interpretations to the mix, this is in line with that fantasy.
I also feel like this is j-culture reminding us that we are hypocrites, although it is probably best not to go into why. Just as well, the 'magic powder' bit is your usual vaguely-described, awkward anime goofiness.
I guess it's easier to pretend that criminal persons of color, LGBT (and more recently portrayals of terrorism)
haven't been getting deleted from games all along since the 90s in order to cater to our delicate western sensibilities. So basically we have lost content, gameplay and sequels for purely political reasons and I don't really think that's cool and I think it's time for a change.
